Specification of Letters Patent.

Patented Jan. IO, 191i,

To all whom it may concern:

Be it known that I, FRED M. Hornins, a citizen of the United States,residing at Muscatine, in the county of Muscatine and State of Iowa,have invented certain new and useful Improvements in Button-MakingMachines, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to improvements in button making machines andmore particularly that type of machines wherein upon the feeding ofblanks of a predetermined character thereto, the same will in a cycle ofoperation of the machine be automatically faced, centered, and, drilledwithout displacing the blanks from the positions they initially occupywhen placed in and held by their carrying chucks, the buttons whensubsequently released from the chucks being in a finished state save foran additional polishing treatment when necessary or desired.

Novel characteristics of my improved machine are the provision of aunitary strncture which includes a series of carrying chucks, facingtools, and drills, the devices of each series being mounted upon asingle traveling support whereby they occupy with respect to each othera relatively fixed or permanent operating position, in contradistinctionto such machines as employ a series of chucks arranged to carry thebutton blanks to facing tools mounted on one support and subseouently todrills mounted on another support, or vice versa; the provision of asingle rotary carrier or support for the several series of devices asaforesaid having a number of bed plates, one for each series, with meansmounted at opposite portions of said plate cooperating with other meanssecured to the upper and lower portions of the rigid frame-work of themachine, to at desired times force the chucks and drills into operativerelation whereby the strain incident to this step of the operation isbalanced at opposite ends of the rotary carrier and. distributedtherethrough and to the rigid frame-work of the machine; means forautomatically and gradually feeding the drill to accommodate for wear atthe point thereof; means for automatically sharpening the point of thedrill, and more specifically means for effecting turning of the drillpoint to secure an even and symmetrical sharpening thereof;instrumentalities for adjusting, automatically sharpening, andautomatically and gradually feeding the face of the tool to accommodatefor its wear;

a brake for stopping the operation of the chucks when passed beyond thefacing tools after the facing operation; and means for automaticallyreleasing the chucks from holding engagement with the button to permitready withdrawal of the buttons from the machine and the introduction ofadditional blanks.

All of the foregoing improvements as also other novel features anddetails of construction and arrangement of parts of a machine made inaccordance with my invention will be mor-e apparent from the detaileddescription hereinafter contained when read in connection with theaccompanying drawings forming part hereof and wherein convenientembodiment of the invention is illustrated.

In the drawings; Figure l is a front elevation of the machine, Fig. 2 isa side elevation looking in the direction of the arrow, Fig. l, Fig. 3is an elevation corresponding to Fig. 2, looking at the opposite side ofthe machine, Fig. et is a horizontal sectional view taken on the line:zz-fc of Fig. 3 and looking in a downward direction, only a few bedplates being shown, and parts being broken away, Fig. 5 is a plan viewof the machine occupying the position shown in Fig. 2, and some of thedevices being omitted for the sake of simplification and clearness, Fig.6 is a detail vertical sectional view of one of the chucks and thedevice for automatically causing the same to open to receive or permitthe withdrawal of the blank or button as the case may be, Fig. 7 is adetail sectional view illustrative of the means for automatically andgradually feeding the drills to allow for the wear at the points of thelatter, Fig. 8 is an enlarged detail plan showing the relativeassociation of parts and means for intermittently moving the chucks andblanks carried thereby to present diiierent portions of the blank to thedrills to secure the desired number of thread apertures therein, Fig. 9is a sectional view on the line Y, Y, of Fig 8, Fig. 10 is a fragmentaryelcvation of Fig. 8, Figs-11, 12 and 13 are a front elevation, sideelevation, and plan, partly in section, of the means for insuring theturning of the drill points for the presentation of opposite sidesthereot to the grinding or sharpening devices thcrefor,`

To impart a general understanding of the operation et my machine, andthus facilitate an appreciation ot the various details as willhereinafter more fully appear, it may be here observed that a completecycle of operations ot the associated parts and mechanisms embracestirst, the presentation of the chuck in open condition to the operatorfor the reception ot' the previously formed blanks, which latter may beof bone, pearl, or other suitable material; second, the automaticgrasping of the blanks Within the chuck to hold the same againstsubstantial displacement or escape; third, the elevation of the chuckinto operative relation to the facing or shaping tool and rotation ofthe chuck and blank against the cutting edge of the :tacing or shapingtool whereby the blank is properly centered in the mouth ot the chuckand also given its predetermined surtace formation dependent. only uponthe character oit the tool employed, and the angular relation of saidtool with respect to the blank being such that in producing such surfaceJiormation it shaves or shears the blank as distinguished from scrapingor scratching the same as is obviously the result where the shapingtool. is disposed in a plane at right angles to that in which the blanklies; fourth, reversing the rotation ot the chuck and shaped blank whilemaintaining engagement ot the blank with the shaping tool whereby themovement of the bla-nk be ing no longer in opposition to the cuttingedge of the tool, the latter is converted into purely a holding orretaining device for the blank while being drilled, and depressing androtating the drill to bore the initial aperture through the blank, afterwhich the blank is turned as an incident to the turning of the chuckintermittently to present other portions of the blank to the drill andapertured in consonance with the conipleinentary intermittent raisingund lowering oit said drill; and linally the presentation ot the drilland facing tool to, and treatment by, their respective sharpening andgrinding tools, It is also to be noted that at suitable points and timesin the operation, the facing and drilling tools are ted by slightgradual movements toward the chuck to maintain them in constantoperative relation thus allowing t'or their necessary wearing away atthe cutting points or edges.

leterring now more specifically to the drawings, wherein corres"endingreference characters designate like parts in the several views, 'lrepresents a pair oi' iiorelegs or columns and 9 a rear leg or columnoccupying a plane centrally between the tort-legs, the same being termedwith suitable iteet 1iL adapted to rest upon any suitable tounda tion,aint L* and 3 top and bottom castings ot V-shaped formation the shorterarms ot' which are rigidly connected to the .torelegs 1 and the longerarm ot which is connected to the rear leg Q. These castings are eachprovided Vwith approimately cenit `ally disposed circular bearings 2 torthe recep tion ot a rotatable shajtt oit a carrier to be soon described,the bottom of the lower bearing being closed by a case-hardened steelplate 3 upon which said shaij't it beurs. YUpon this shatft 4t arerigidly secured so as to rotate, therewith a series' ot rings or disks,three beingl shown, the top one otf which is indicated at 5, the lowerat 7, and the cen tral or intermediate one at (l, and arranged aroundthe peripherics ot these rings or disks are a plurality ot bed plates tl(coin veniently twenty-one in nmnber) each ot which carries anindependent series olf but ton `working in'iplements. 'i`hesebed-platesl with the series ot button Nori-:ing implements carriedtherebyv may each be styled z separate and complete button blanktreating unit.

Any means found exlledient may be ein plo;l l to rotate the shajtt itand iinnlemcnt carriers thereon, that shown consisting et u worm 9meshingl with a, worm wheel l() on the shaft -il-, the shat't o et theworm being mounted in suitable boxes o/ on the rasline il, and driventhrough the nxediiun ot a pul ley n at the end ol said shutt which isgeared by a belt a to a pullerY fr* on the main drive shai'ft oit themachine ci, to which lulter a drive wheel or pulley B receiving` itspower from any convenient source is secured. rlhe pulley a may bereudil)7 connected with or disconnected from the shaitt when it isdesired to start or stop the rotution ot the shaft -lf and the carrierthereon. by a clutch C shittuhle by a lever C.

Revel-ting to the Supportiimj or bed plalc t3, it will be seen that eacholf these carries the lower portion therco't an upwardly l il t .llO

facing chuck 11 and at its upper portion an oppositely disposed drill12, while occupying an angular position intermediate the chuck and drillis a facing tool 13. The chuck consists of a number of segmental jawsectionsD having rims (l for grasping the periphery of the blank orbuttons, each section having an elongated shank d and outwardly beveledor inclined shoulders d, the shoulders being normally engaged by theupper end of a sleeve (Z3 which, working under the pressure of a spring(Z4, force the jaw sections together and into engagement with thebuttons or blanks and effectively hold the latter' in place. rlhe springd* just referred to abuts at its opposite end against an offset Z5 uponthe interior of a tubular holder (ZG (see Fig. G) an adjusting bolt (Z7having threaded engagement with the lower closed end of this holderwhereby the chucks are afforded an adjustable abutment for engagement bytheir elevating devices. rIhe chucks are secured in place on the rotarycarrier by means of collars 1st bolted to the plates 8 and embracing theholders of the chucks. A pulley 15 on the holder (ZG of each chuck isprovided to rotate the chuck at proper times during the rotation of therotary carrier, such rotation being dependent upon the elevation of thechuck into the horizontal plane of, and engagement with, a driving belt1G (Fig. 4) passing around a drive pulley 17 and an idler 18, the latterbeing mounted upon one of the forelegs or columns 1 through a bracket18a, while the former is secured to and rotates with a sleeve 1S) on thecolumn 2 receiving its movement through the medium of intermeshingbeveled gears 19a, 19h, one rigid with the pulley 1T and the other rigidwith the shaft a. of the main drive wheel B. The elevation of the chuckas suggested is etl'ected by means of a freely pivoted angular orbellcrank lever 2O mounted at the lower end of the bed plate S. theupper or horizontal arm of which abuts the lower end of the chuck ormore specifically the adjusting bolt (Z7 thereof, while the vertical ordepending arm of said lever travels around and engages a horizontallyarranged cam 21 rigidly secured in any desirable manner to the casting8, the securing means preferably eniployed and shown in the drawingsincluding a ring 2la bolted to said casting and adj ustable bolts 2lbpassing transversely therethrough and carried by the sections of the cam21 whereby the latter may be properly adjusted in an obvious manner.

A brake E secured to an upright c bolted to the rear arm of the casting3 is arranged within the path of movement of the rotating pulleys 15 forthe chucks whereby the rotation of the same and chucks is stoppedimmediately upon their traveling beyond and out of engagement with thebelt 16.

ln the same vertical plane as each chuck, and arranged so that it willimmediately engage the blank therein upon elevation of the chuck beforementioned, is the facing' tool 13, the latter, as will be readilyappreciated from the drawings, being mounted on and carried by the bedplate t3 whereby it is angularly disposed with respect to 'the chuck andbutton blank therein to enable the tool in facing the blank underrotation of the latter to act thereon with a clean shaving or shearingcut, the results of which. I have found are far superior to thoseobtained by tools placed at right angles to the. plane of the blank andby which the blank is simply scraped or scratched to the surfaceconfiguration sought. rlhe details of this centering and shaping toolwill now be described particularly, reference being made to Fig. 15. Thebed plate 8 has a transversely disposed inclined aperture f throughwhich a tubular holder F :tor the tool 1&3 passes, the end of thisholder outside of the plate 8 being formed to a bracket f havingenlarged apertures f at the three corners thereof for the reception ofsecurii'ig boltsl f3 having threaded engagement with the bed plate S,and said bolts being of a diameter considerably less than that of theapertures f whereby the bracket f and holder F may be adjusted in anydirection within a given limit of movement to bring the tool 13 intoproper position relatively to the other devices of the machine, theadjustment being maintained through the medium of locking bolts f*adjustable through threaded apertures in the edges oilI the bracket vtto bind upon the securing bolts l7C. Projecting out vardly from thebracket f is a lug or seat f5 upon which rests a laterally adjustableslide f having a longitudinal rib fl fitting a complementary groove inthe inner face of the shank of the tool 1?; whereby the latter may slideupon said rib and be adjusted lengthwise thereof whileA being heldagainst lateral movement independently of the slide f, the lateraladjustment of said slide and tool being obtained by adjusting bolts f*engaging the edges of the former. A back plate t holds tht` tool inplace on the rib f7, said back plate being in turn held in place byyieldabh` fastening devices in the nature of adjustable springpressedbolts fm. A screw threaded plunger (lr bears upon the upper end of theshank of the tool 13 and is designed when forced downwardly thereagainstin a manner to be now dened to cause a gradual outwardly sliding orfeeding movement of the tool to accommodate for the wearing away of thccutting points thereof. The plunger is groo ved longitudinally as at forthe reception of a spring-pressed pin g which will prevent rotationthereof. rllhe means for feeding the plunger comprises an internallythreaded sleeve g flanged at its lower end g3 and held in place betweenthe shoulder g4 on the holder F and retaining ring g5 by screws gcfastened through the holder and into the retaining ring; a worin wheel Hsecured by a bolt i to the threaded sleeve g a worm I meshing with saidworin wheel; and a star wheel z' on said worm so arranged that in itstravel with the rotary carrier around the machine it will come inengagement with a detent 22 suspended from the upper casting 2 whichwill turn the star wheel the extent of one tooth thereof andcorrespondingly feed the facing tool.

Remembering that the facing tool completes its function as such duringthe period of engagement and rotation of the chucks by the belt 16 andthat the rotation of chuck is stopped by the brake E immediately upondisengagement of these parts it will be seen that the faced blank is nowready for the drilling operation te make the thread apertures in saidblanks and during this operation, as will hereafter more clearly appearthe facing tool is converted into a holder, or retaining device for theblanks. As has heretofore been brought out 12 indicates the drills, oneon each bed plate 8 arranged di rectly above the chucks and facing toolthereon, the drill being secured in place by a bracket 23 adjustablymounted on said bed plate and having bearings or collars 2Liin which thedrill chuck or holder may slide vertically. T he drill has a drivingpulley 25 and is normally held upwardly out of opera-- tive relation tothe work by a coil spring 26 bearing at its lower end against the lowerbearing or collar 211 of the bracket 23 and at its upper end against theunder surface of said pulley 25, the latter of course being rigid uponthe drill holder or chuck. The rotating means for the drill justsuggested comprises a driving pulley 27 on the rotatable sleeve 19around and from which a belt 28 (Fig. 5) passes to an idler 29 on one ofthe fore legs or columns 1, an adjustable slack take-up device 30 beingalso mounted for adjustment upon one of said fore legs 1 and engagingthe outer run of said belt. At the proper time the drill holders aredepressed to bring their drills into operation on the blanks, thedepressing means in this instance being in general respects the same asthe elevating means for the chucks herctofore defined in that the sameincludes an angular or bell-crank lever 31 freely pivoted at the upperend of the bed plate S whereby its horizontal or lower arm will engagethe upper end -of the drill while its vertical or upper arm willsuccessively engage a number of cams 32 adjustably secured through themedium of bolts 32a and a ring 32b secured to the top casing 2 of theframe of the machine, the number of these cams differing according tothe character of work to be performed, four appearing in the presentinstance inasmuch as the machine disclosed herein is designed to drill alike number of holes or apertures in each blank. Now as the drill issuccessively depressed under the infiuence of the cams Elif, andVagainst the tension of the restoring or elevating springs 26, some meansmust be provided for turning the chucks and blanks carried thereby topresent the different poi-tirasy of the blank to be bored to the drills,it being understood that the parts are so arranged. that each of saidturning movements takes place while the drill is elevated intermediateits depressing movements by the cams 32. The turning means will now beconsidered. A segmental guide plate 33 is secured at one end to one ofthe fore legs 1 of the frame by means of a bracket 33 and supported atits opposite end and between its ends by posts 33h (Figs. 2 and Ll) tooccupy a position slightly above the plane of the upper surface of thepulley 15 of the chuck when the chuck is in raised position whereby inthe movement of the rotary car rier the inner edge 33 of this guideplate will engage pegs 3/1 projecting upwardly from said pulley. Uponthe initial eng ment of the chucks with this guide plate and while thefirst hole is being` bored through the blank, it will be observed th attwo of the pegs 34,of which there are four arranged equidistantly apartand from the center of the (hneln-will simply ride along the edge 33C ofthe guide and prevent turning` of the chuck. As soon, however, as theforemost peg in the line of travel of 'the cari'iei.' comes intoengagementwith the jaw 35 of a pawl 35 pivoted on the guide 33, said pegwill be temporarily held in opposition to the movement of the carrierand the chuck thereby rotated one-quarter turn until the nextadjoiningpeg contacts with the edge when the peg previously caught by the pawlwill ride out of engagement with the pawl which has in the meantime beenpushed aside (see Fig. S), the inner edge of the guide plate being cutaway as at 35h for that purpose. rl`he chuck will then be held againstfurther turning movement until engagement is made with the next pawl andin the interim the second hole will have been bored in the blank. Now ifthe pawl. be jierinitted to remain in the position in which the caughtpeg 34E leaves it, v'. c. pushed aside from the edge 33C it would not beiu projiier position to engage the pegs of the oli-coming chuck; and toinsure that the pawl shall be posif tively returned to its initial oroperating position l provide the same with a tail piece 35 adapted toproject inwardly beyond said edge 33 into the path of niovement of thereleased peg 311 so that the peg will force said tail piece outwardlyand. thereby rock the jaw of the pawl inwardly n) ef to the desiredposition, to properly engage the nearest peg of the ori-coming chuck, astop 35d being afforded to limit the outward movement of the tail piece35c and inward movement of the jaw 35a. The operation of the succeedingpawls no matter how many in number, being the same as thatjustdescribed, they need not be further referred to. A. feature,however, to be noted at this point is that the rotation or turning ofthe chuck while traveling along the guide plate 33 and under the actionof the pawl 35 is in a direction just the reverse of that while thechucks are rotated by the belt 1G, so that although the facing tool 13is still in contact with the blank theretofore acted on thereby, theblank no longer moves in oppo! sition to the cutting edge of said facingtool but slips freely around underneath the same and from the backthereof. Thus the facing tool is converted into and operates during thedrilling operations as a holding device for the previously faced blankcarried by the chuck, n

Vl`he stubs or pegs 34 are removably cured in the pulley 15 (Fig. 9)through the medium of apertures 3l? furnished for the reception of theirinner ends in said pulley and binding ssrews Selb screwed through theperipheral portion of the pulley into the pegs. From this view itwillalso be seen that the pulley is in turn made fast to the chuck holder dby a large binding screw (ZS passing through an internal flange orcollar d" of the pulley and introduced through. an aperturevl10 in therim thereof. The means for securing a gradual and automatic downwardfeeding of the drill to allow for the wearing away thereof at thepointeml'xraces mechanism associated with the bell crank lever forobtaining a slightly increasing depression of the drill under the actionof said lever and the cam which engages it a nd comprises a presser foot3G. the shank of which is slotted as at 3? and sleeves through the loweror horizontal arm of the lever whereby vertical movement otl the presserfoot may be had, a pin 33 carried by a spring 365 on the lever andentering the slet 3'4" preventing turning and escape thereof. and aninternally threaded worm wheel 3E? meshing with a star wheel and detentcontrolled worm 4C' constituting the means for lowering the presser footin the lever. The star wheel represented at ll and the detent at 112,the former being mounted on the shaft of the worin 40 and the latter onthe upper casting 2X, so that the star wheel. is turned the extent ofone tooth at each revolution of the machine.

titer the button blanks are faced and drilled. means should be providedto antonuitically release the grip of the chucks upon the buttons tofacilitate their withdrawal from the machine and the introduction ofuntreated blanks in lieu thereof, and for this purpose l employ aninwardly flanged or angle iar beveled at its edge 43a and secured by abracket t. to one of the forelegs 1 in a position to extend around aportion of the front of the machine and into the path of movement of thechuck after the drills have receded therefrom and the chucks lowered,whereby the edge 43a will engage and force in vardly the sleeve o of thechuck against the tension of the spring d'4, thus permitting the jawsections D to spring apart or separate. 'The facing tool 13 is keptbright and keen by an emery or other wheel 45 with which the toolcontacts in the rotary movement of the carrier, the wheel beingsupported by a bracket Llr6 on one of the forelegs 1, the bracket havinga pair of bearing` boxes e7 for the shaft 43 of the wheel, and a pulley449 by which the wheel maybe rotated from any convenient source of powerbeing carried by said shaft 4S between the boxes 4J. Sometimes it isdesirable to adjustthe boxes el? and to enable this to be done thebracket 4G has corner bearings 50 for the boxes slotted as at 51 for aguiding and binding' screw and apertured and threaded at 53 for thereception of an adjusting bolt 54. (See Fig. 19.) By thus enabling aready adjustment of the emery wheel, the same may be quickly advanced tomaintain an operative relation to the facing too-l as the wheel. wearsaway.

Means are also provided for sharpening the drills 12, and the sametogether with the instrumentalities for causing proper presentation ofthe drills thereto will. now be described.

55 and 56 are grinding tools, the former having a straight peripherywhile the latter has a beveled periphery, mounted upon one of thecolumns 1 by brackets 57 in such position as to operate both on the sideand point of the drill as it passes thereagainst in the rotation of thecarrier. These grinders are rotated by pulleys 58 driven by anyconvenient means. To alternately present the different sides of thedrills to these grinding wheels and 5G in the successive rotations ofthe carrierr` l employ mechanism for turning the drill by a step-by-stepoperation as the same approaches the grinders and for holding the toolin a. fixed position vvhile being engaged by the grinders, suchmechanism including the following devices: is a vertically disposed camrotatable on av shaft (30 carried by a bracket 61 rigidly se cured toand depending from cross bar (32 mounted upon the fore legs 1 of theframe of the machine and spanning the space therebetween, this cam beingdesigned to elevate cr permit lowering of a sleeve G3 slidably mountedon bracket G1 the latter having a projecting flange Get arranged to rideupon the operating edge or periphery Cil of the cam. The cam is rotatedstep by step in successive rotations of the rotary carrier by a pin G5projecting outwardly trom the bed plate 8 which carries the pin G5sutlicient distance to engage the inwardly projecting pins 66 on thecam. 67 represents a yieldable horizontal spring metal guide carried bythe flange 64 of the sleeve 63 adapted when the sleeve is in its uppenmost position raised thereto by the enlarged portion o1a the cam 59 tocontact with the flat surface GS of the upper rim 69 of the drill pulley25 to prevent said drill pulley and drill from rotating, and when in itslowermost position whence it falls by gravity onto the reduced portionsof the cam incident to the rotation et the latter, to correspondinglyengage the flat surface 70 ot the lower rim 71 of said pulley 25 andsimilarly hold the pulley and drill against rotation. Dependent upon theposition of the guide 67, that is, whether the saine be engaging` theflat surface of the upper or lower rim, the drill incident to thecontinued rotation ot the carrier will be similarly carried intoengagement with other guides 72, 73 which will hold the drills againstrotation while in engagement with the grinders 55 and 5G, the guide 72being arranged above the plane of the guide 73 and in the path otmovement ot the pins Tl on the top oit the pulley 25 while said guide 73is in the path of movement ol2 pins 75 on the bottom of said pulley.rlhere'tore, presuming that the yielding guide on the sleeve G3 is in aposition indicated in 12 and 13 with the tlat. edge 68 et the rim G9 ofthe pulley engaged thereby, the drill without further rotation will passinto engagement with the upper guide 72 by alined pins Tl ridingthereonto and the drill will be held in such position while passing thegrinding wheel 55. The pins t then passing beyond the guide 72 permitsengagement ol the lower guide 73 by the lower pins 75 whereby the drillwill be turned and held in position while presented to the grindingwheel 5G. It will thus be seen that by this operation one ot the sidesot the tool is sharpened and one ot the ends beveled, sharpened anddiamond pointed. ln the next rotation ot the can rier the pin G5 willengage the pins titl ot the cam and rotating the latter the sleeve 63and guide 6T will be lowered troni the position shown in Figs. 12 and 13as aforo said whereby the guide will engage the oppositely disposedstraight surface 7G of the lower rim 71 of the pulley thus rev-ers ingthe position occupied by the drill in the previous rotation whereby thenext presentation of the drill to the grinding wheels will effect thesharpening of the other side ot the drill and the beveling of the otherside ot the end of the drill and thus maintain a diamond point on thedrill. Thus it will be appreciated that in two revolutions ot the rotarycarrier all cutting edges ot the drill are presented to and acted on bythe grinding wheels.
